New investigation Development of the Dai Yuan method for solving Unconstrained Optimization Problems.

In this paper, by making some modifications to the Dai-Yuan method, we propose a new method to solve large-scale unconstrained optimization problems due to its simplicity and low need for memory. In addition to the comprehensive regression and convergence properties of the proposed method, the proposed method was compared with classical methods. There are researchers who have worked on developing and modifying the Dai Yuan method within their theses Among them is Hoda -Younis [15] and others."
